What is the cultural value of calligraphy?

China's 5,000-year splendid civilization and unparalleled rich written records have been recognized by the world. In this long and profound history, China's calligraphy and painting art reproduces this diachronic evolution process with its unique artistic form and artistic language. In the historical evolution, calligraphy and painting, a sister art, explained the traditional cultural connotation of China with its complementarity and independence. Because the tools and materials used in the creation of books and paintings are the same. When talking about the origin of ancient Chinese characters and paintings in China, he said: "At that time, books and paintings were the same, but there was no difference. The image system is too subtle to convey its meaning, so there are books; There is no way to see its shape, so there are paintings. " Although calligraphy and painting are homologous and comparable, their future development and changes are complementary and independent. The formation and development of China's calligraphy art is closely related to the emergence and evolution of Chinese characters. So what exactly is "calligraphy"? We can understand it from its nature, aesthetic characteristics, source and unique performance. Calligraphy is an abstract symbolic art based on Chinese characters and written with a brush, which has four-dimensional characteristics. It embodies the basic law of the "unity of opposites" of all things, and reflects the spirit, temperament, knowledge and cultivation of people as the main body.
